Leve it to stand for 30 min start it up and it's back in the hi 40,s lo 50,s on tick over
What doesnt seem to add up is that when warm, you have 40psi tickover and it goes up to 40-50psi driving.
Minimum cosworth oil pressure should be 24psi. I have seen just about below this (like you) when coming off track after a 20min session. But it soon recovers to between 25-30psi. Not an issue IMO.
Looks like you have a std pressure oil pump.
A high pressure one should give 20psi more (driving pressure), warm idle pressure stays the same.
